summary    = A GNU arbitrary precision library.

description
	The gmp package contains GNU MP, a library for arbitrary precision
	arithmetic, signed integers operations, rational numbers and floating
	point numbers. GNU MP is designed for speed, for both small and very
	large operands. GNU MP is fast because it uses fullwords as the basic
	arithmetic type, it uses fast algorithms, it carefully optimizes
	assembly code for many CPUs' most common inner loops, and it generally
	emphasizes speed over simplicity/elegance in its operations.
